I need the flow of calls.
Thank you Giovanni
gprof will do this on Linux/BSD if gdc supports the -pg flag (I
don't know whether it would, but assume so) and your
application is working.
From code, you'd need to call a trace function on function
entry. Mine lets you also specify a message (parameter values,
etc.):
---
void trace(T...)(T args, string func = __FUNCTION__) {
import std.stdio : writeln;
if (args.length > 0) {
debug writeln("*trace: ", func, "- ", args);
} else {
debug writeln("*trace: ", func);
}
}
void main(int a, string b) {
trace();
trace(a, ", ", b);
}

You can also generate a call graph using callgrind.
That however will slow down your program.
There are some python script that converts the output of
callgrind to a dot file that can be converted to svg.
